Abstract :
An extension is given to Kalman observer theory which gives necessary and sufficient conditions for reduced-order Kalman observers for the case when it is required to observe a specified linear functional of the states of a system rather than the states themselves. The results are useful for the design of low-order compensators for systems with noisy output measurements.
